Tracking Industrial Land Use Conversions: A New Approach for Studying Relict Waste and Urban Development.

Research on urban development and environmental hazards has focused attention on problems associated with current industrial facilities, derelict industrial brownfields, and government-listed hazardous waste sites. Yet we continue to know very little about environmental contaminants remaining on past industrial sites that have since converted to other uses. This article develops a methodology for examining the prevalence of such sites and their historical conversion and then presents an illustrative case study of this methodology for New Orleans, Louisiana, from 1955 to 2006. Contrary to expectations, results show that most sites occupied by polluting industries in the past have since converted to other uses and that this conversion is most common in predominantly White neighborhoods. These findings extend and complicate extant research on urban industrial hazards and environmental justice, calling attention to the potential accumulation of historically generated contaminants not just in identifiable brownfields and lingering industrial corridors but also in neighborhoods throughout older cities.
